such as will enable others skilled in the ar to which it'appertains to make and use the same.

My invention relates to the type of fur-1 naces which discharge heat into a room from a central heat discharge pipe and take fresh air into the space "within the shell 'of the furnace through'a cool air acket which surrounds said pipe. The principal object is to provide an improved means for forming the jacket in a simple and inexpensivemanner and at the sainetime to provide means for reinforcing the sheet metal top of the furnace shell 'to prevent warping thereof which would otherwise'distort the grating usually disposed. over the-,upper ends of the heat discharge pipe and the cool air jacket.

With this general object'in View, the in vention resides in certain novel features of construction and in unique combinations of parts to behereinafter fully described and claimed, the descriptive matter being supplemented by the accompanying drawings which constitute a part of this application and in which:

Figure 1 is a vertical section of the improved furnace showing its application to a heating system in accordance with my invention; p t i Fig. 2, is a vertical section taken at right angles to Fig. 1 as indicated by the line 2-2 of Fig.1; 5

Fig. 3 is a horizontal sectional view taken on the plane indicated by the line 3-3 of Figs.1and2; 1 g f Fig. 4 is a perspective View of the upper heat radiating ring of the furnace; and

Fig. 5 :is a similar View of the lower ring. In specifically describing the construction shown in the drawings above briefly referred to, similar characters indicate corresponding parts throughout the several vlews. The

numeral 1 designates a furnace proper which may be of any suitable construction pro vided with a dome-shaped upper end 2 ha ing diametrically opposed smoke outlet openings 3. A lower heat radiating ring 4: surrounds and is spaced from the dome-shaped upper end of the'furnaee, said ring being hollow and having projecting radially inward from its inner side a pair of smoke passages in the form of rectangular necks having inclined inner ends (3 which rest on the sides of the dome-shaped upper end of the furnace, said necks registering with the openings 3 as shown most clearly in Fig. 2 and preferably having laterally extending flanges or the like 7 by means of which they are secured to the furnace.

in upper radiating ring 8 of hollow for-- mation is spaced above the ring *1, said upper ring having a pair of depending smoke passages 9' which telescope with similar passages 10 rising from diametrically opposite points on the ring 4, one of said passages 9 having a damper 10 which may be opened when building a fire in the furnace 1, it being however normally closed, (see Fig. 2). Both the upper and lower rings are provided with clean-out passages 11 closed normally by doors 12, and the upper ring 8 is equipped with a smoke discharge neck 13, which latter communicates with the smoke pipe l-i leading to a flue 15.

A cylindrical heat trap )ing shell 16 surrounds and is spaced rom the furnace proper'and both of the heat radiating rings above described, the clean-out passages 11 of said rings and the smoke discharge neck 13 opening through said shell as clearly shown in Fig. 2. Dead air spaces for insulating purposes are eliminated in the improved furnace and in lieu thereof the shell 16 is lined with asbestos as: shown at 17 and a corrugated lining 18 of bright tin is secured in contact with the inner surface of the lining 17. The upper end of the shell 16 is preferably reduced gradually in diameter into a somewhat frusto-cone shape, and said upper end is provided with a top 20 having a single opening 21 from which a hot air discharge pipe 22 rises.

A polysided wall 23 surrounds and is spaced from the pipe 22, forming therewith a cool air jacket, said jacket having its lower end closed by the top 20, this being preferably done by forming latarally extending flanges on the low'eredges of the wall 23 and by bolting .or riveting said flanges to the top 20"as indicated at 2-4. A grating 25 extends over the upper ends of the pipe 22 and the wall 23, said grating allowing hot air to be discharged from said pipe while permitting cool air to enter the aforesaid jacket though not necessarily a lower hall. By this means. This affords a better circulation of,

from which it is led through a pair of pipes,- 26 into a main upright passage 21', the lower end of said passage delivering into a shoe 28- which is in communication with the space ing preferably secured in place by the same means which anchors the aforesaid jacketto the top 20.

A second'cool air passage 31 discharges into the space within the lower end of the shell 16 (see Figs. 1 and '3), said passage having at its upper end a grating or the like 32, while a fresh air inlet 33 leads into either the passage 27 or that-indicated at 31, preferably the latter.

adapted to extend from the open air and is provided with a damper 31 whereby the amount of fresh air entering the space within the furnace jacket 16 may be controlled or altogether checked.

in a furnace roomF-R and the grating 25 will be positioned in the floor F ofa room R above the furnace room. The grating'32,

however, will be disposed in the floor F of a room R, the latter room being preferably arrangement, hot air will be discharged from the furnace into the room R and simul- 'f taneously with this operation, cool air will be drawn from'said room and from the'room R. to be reheated, it being understood that the two rooms are in communication through means of transoms, doorways or other air and consequently more efficient ventila-v tion, and at any time fresh air may be admitted into the system by operation of the damper 34, which latter may wellvbe so constructed as to allow it to be actuated from the first flo'or of the building.

A water pan 35 is located within the shell 16 in order to supply the proper amountof moisture to the hot air expelled from the furnace, water being supplied to said. pan through a pipe 36' which leads from a' second pan 37 on the exteriorof the furnace, said pan 37 being, preferably supported by a bracket 38 extending from said furnace as shown." A reservoir or supply tank 39rises within the pan 37' andf'is provided with a valved water inlet pipe40iwhich may be used in buildings having running water therein, said tank however,- being also equipped with a screw cap or the like 41 whereby it maybe filled by hand. The lower The inlet 33 is end ofathe tank 39 has one or more outlets 42 delivering into the pan 37, whereby ,as

long as the water level in said pan is above *s'said outlets, a1r cannot enter the upper end of the tank and consequently, no more water can be discharged into the pan. However, when the water level in the latter lowers, due

- to evaporation in the pan 35,, the outlets 42 will be exposed with the result that air will. enter thetank 39 through said outlets and will thus allow water to be discharged to again'raise the level in thepan 37 to its normal position. Thus, an adequate amount of water will be supplied'to .the pan 35 at all times with the result that sufiicient moisture will prevail in the heated air discharged from the furnace.

The tank 39. may have any desired capacity but it will preferably contain anywhere from ten to thirty gallons in order that the supply of water therein need not be often replenished In Fig. 2, the upper end of the shell 16 is shown as provided with a collar 50 from which aheat conducting pipe 51 may lead I to any part of a building, said pipe preferably having a damper 52. In use the improved furnace will be placed tages of my improvements will be readily understood without requiring .a more ex-' tended explanation. In conclusion, however, I wish it understood that although certain specific details of construction have been E shown and described for accomplishing prob-.

ably the best results, numerous changes may claimed. Iclaim:

Y The combination of a heater, a cylindricalvertically disposed shell surrounding and be made within the scope-of the invention as spaced-from thesame, a sheet metal top for said. shell having a single central opening, a short heat-discharge pipe rising from said opening, a grating extending over and horizontally beyond the upper end of said pipe, and a unitary polysided wall surrounding said pipe and spaced therefrom, said wall extending the entire distance between said grating and the top of the shell, the corners of said wall resting on the edge of said top over thecurved wall of the shell and the lower edge of said wall having integral outstanding flanges secured rigidlyto said top to prevent sagging thereof.

, In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
